Vonage, the VoIP telephone company, released their iPhone and Blackberry applications today. You might wanna reserve your excitement,though, since this application does not work with preexisting Vonage accounts that cost $25 a month and provide unlimited calls in the US and up to 60 countries.
Nope, the Vonage app will make calls over your cellular (and/or WiFi if on the iPhone) connection to international numbers at a significant discount (up to 50%) when compared to what AT&T or other carriers offer.
In an ideal world you’d be able to use the Vonage Mobile app for the above as well as have the ability to connect to the Vonage home phone service that allows you to make unlimited calls around the world using your home’s Internet connection. And at this point it seems unlikely that Vonage will ever provide this option since it will cannibalize the sales of their Vonage equipment. Booooo!
